摘要：

由于油藏不同开发阶段特征及其研究目的不同，三维地质建模中层面建模采取的模拟方法和模型精度均有所区别。从三维地质建模角度出发，将油藏开发划分为油藏评价、新区建产和老区调整3个阶段，通过港东二区五断块层面模拟过程中各种模拟算法分析及筛选，提出了层面模拟时，油藏评价阶段建模采用Kriging算法，网格精度为100 m×100 m×5.0 m；新区建产阶段建模采用Kriging算法或Global B-spline算法，网格精度为50 m×50 m×1.5 m；老区调整阶段建模采用Local B-spline算法或Converging average算法，网格精度为10 m×10 m×0.5 m，使层面模拟结果更符合地质情况及研究需要。

Abstract:

The simulation methods and model precision adopted for layered modeling in 3D geological modeling vary with reservoir characteristics and research purposes at different development stages. From the perspective of 3D geological modeling，the reservoir development can be divided into three stages: reservoir evaluation，new block development，and existing block adjustment. The layered modeling algorithms were analyzed and selected for the 5th fault block in Gangdong district 2. It is proposed that the Kriging algorithm should be used for modeling at the reservoir evaluation stage，with a grid resolution of 100 m × 100 m × 5.0 m；the Kriging or Global B-spline algorithm should be used for modeling at the new block development stage，with a grid resolution of 50 m × 50 m × 1.5 m；and the Local B-spline or Converging average algorithm should be used for modeling at the existing block adjustment stage，with a grid resolution of 10 m × 10 m × 0.5 m. This modeling approach can provide results in more coincidence with actual geological conditions and can meet requirements for reservoir research at each stage.

Key words: reservoir development, stage division, layered modeling, simulation algorithm, standard layer, reservoir evaluation, new block development, existing block adjustment
